Abstract

ObjectiveTo examine the relation between uterine blood flow and endometrial thickness on transvaginal Doppler ultrasonography, serum E2 and progesterone levels, and the histologic dating of an endometrial biopsy specimen obtained in the midluteal phase of a spontaneous cycle.DesignProspective clinical study.SettingA tertiary care infertility center.Patient(s)One hundred fifty-nine patients with normal menstrual cycles.Intervention(s)Transvaginal Doppler ultrasonographic evaluation of uterine blood flow and endometrial thickness, determination of serum concentrations of E2 and progesterone, and endometrial biopsy.Main outcome measure(s)Resistance index, pulsatility index, serum E2 and progesterone levels, endometrial thickness, and histologic dating of the endometrium.Result(s)One hundred thirteen (71%) of the endometrial biopsy specimens showed complete secretory transformation and thus were classified as "in phase," and 46 (29%) of the specimens lacked some or all of the criteria for secretory transformation and thus were classified as "out of phase." There was no statistically significant difference between the in phase and out of phase groups with regard to patient age, endometrial thickness, serum hormone levels, or resistance index. The pulsatility index was significantly higher in the in phase group. The overall predictive value of the studied parameters was only 64% (sensitivity, 57%; specificity, 66%).Conclusion(s)Doppler ultrasonographic evaluation of uterine blood flow and measurement of hormone concentrations cannot be used to predict the histologic dating of an endometrial biopsy specimen obtained in the midluteal phase of a spontaneous cycle.
